Existing studies have shown that there is a certain correlation between high production quality and low soil nutrients, and there is a regularity in soil nutrient change and age in tea gardens. However, studies on the growth and adaptability of soil nutrients have not been reported. Using the soil nutrient data of Guangxi Camellia oleifera production area, using soil nutrient fastness instrument analysis and index and evaluation methods, combined with Camellia oleifera quality data to obtain the spatial distribution characteristics of Guangxi Camellia soil nutrients, as well as soil nutrient suitability evaluation results of Camellia oleifera plantation, planning for high-quality Camellia planting Provide theoretical basis.
In the spatial analysis, the soil nutrient fastness tester statistically analyzes the soil nutrient index. The coefficient of variation reflects the degree of dispersion. According to the research content of the study area and data capacity variation, there are different standards. According to the research content of this paper, the coefficient of variation is less than 0.1. Weak variability. The soil pH, organic matter, total nitrogen, available copper, and available iron content were moderately spatially correlated. The remaining indicators had poor spatial correlation. This may be caused by objective factors such as the complexity of soil parent material and topography in the Camellia oleifera production areas in Guangxi. .
According to the results of the correlation analysis of soil nutrient fastness tester, 8 soil nutrient indexes such as pH, total potassium, available potassium, exchangeable calcium, effective copper, available zinc, available boron, and effective manganese, which have a great influence on the quality of oil camellia, were selected. As an indicator of soil suitability. Because the influence of the selected nutrient index on the growth of Camellia oleifera was different, the weight of each nutrient index was calculated using the principal component analysis method according to the importance of each index.
The requirements of nutrient characteristics of Camellia oleifera and the soil nutrient fastness tester were used to determine the soil nutrient grading standard of Guangxi Camellia oleifera. Based on the grading standard, different soil nutrient indicators were assigned to the corresponding grade points. According to the index weights and rank scores, the expansibility evaluation index of Camellia oleifera soil was calculated according to the index and method, and then the soil suitability index and range of Camellia oleifera were divided according to the gradient segmentation value. The regions corresponding to the indices were the nutrient suitability of Camellia oleifera soil. Partitioning, for ease of analysis and practical application, the results are divided into the most appropriate, more appropriate and inappropriate 3 partitions

In addition to strength equipment and aerobic equipment, the gym also has some essential fitness accessories. These gym fitness accessories can play a good auxiliary role and meet more exercise needs.
Common fitness equipment accessories include:rubber coated dumbbell,rubber straight and curl barbell,Olympic bar,weight plate,colorful kettlebell,rubber floor,aerobic step,gym ball,medicine ball,yoga mat,battle rope,sandbags,etc.
What is a fitness accessory?
Accessory exercises, sometimes referred to as secondary exercises, generally follow on from the so-called 'primary' or 'compound' exercises. They often allow you to focus on different muscle groups or hit certain muscle groups in different ways.
What is accessory work in the gym?
Accessory exercises are complementary movements you do in addition to your core activities (for example, the bench press, squat, and deadlift) to accumulate additional training volume, build muscle, improve your performance, and enjoy more varied workouts.
What Gym Equipment should beginners use?
Best equipment for Beginners
If you're really stuck, try programming half a session using free weights, focusing on compound lifts like squats, deadlifts and chest press with dumbbells and kettlebells, followed by some time on your favourite cardio machine, aiming for 10-15 minutes of intervals.
